Thanks Yogesh_rf !
could you explain me what should i check concretly.We have Ericsson BSS. We have also experience an increment in the Interference in Uplink in the band3 and band2 and in the CHGR1 where are the TRX with hopping, the RxQUAL is bad (in some cases 6 and 7).
We have the same HSN for all sectors and diferents for each BTS and MAIO are also well separately. We have for SFH just 18 freq. Could you recomend me a well distribution of maio for a site configuration 4-4-4 .Thank you very much .Lucka
